' To au 'whom 'it may concern;

vBe it known that L G-es'rev il; Genen n citizen of 'the United States, resi StLouis and the State oiE liliesouri,

invented a. new end useful iniproven'aent in.

Refrigerators, of which the following; is a full, clear, and exeot Speeitiefe'vtin'mj reference being bed to the eeeoinpenying drawings, which forni e part thereof.

' 'My invention relates to refrigerators in which the Cooling ie brought moet lee or preferably a mixture of ioe and eelt in a container in the .refrigeretorn The. object of my invention ie to provide a form oi tank in the refrigerator in which '20 e zig-zeg path through the tank from ies the Water or brine from the oonteiner sbell be caught and retained or e time, eo ne to eid inv Cooling the interior ott the redigereytor, by making the Water or brine travel piece of entrance thereto to tbe plone of exit therefrom; and e further obieet of my invention is to provide e tank for oeteliine Water or brine from the container Wlfiien shell be eo constructed that the brine will be admitted to the lowerpert of tile tenir,

The tank may be mede of any convenient size or shape and be supported in eny suitable manner, and the drip-@ian nitty be supported in any suitable wey to ceteb. the brine from the container B.

l/Vhzit claim as new and, desire to Secure by Letters Patent, is:

l. A. refrigerator comprising o casing, e container for ice and salt having an opening through which brine may drain, e brine tanlig'e trough, e' rippen adapted to catch `seid. trough, an inlet meente the brine from Seid container sind discharge it into said trough, an inlet pipe having its lower end connected to said tank and its upper end adopted to receive theI brine rom said trough, un overflow pipe for Said tank, and baiiics in said tank between seid overiiow pipe and said inlet pipe.

2.- refrigerator comprising e casing, a container for ice end salt having un openingtlirougli which brine. moy drain ny brine tank, e., trough, :i drip-pen odapteni to catch the brine from er1-id container and discharge it into euiol trough, an overflow pipe for pipe having its lower end connected to seid tank and 'its upper end adapted to receive the brine discharged from sind overliow pipe of Said trough, o sealed overflow pipe for said tank, and.V

. vertical beiie plates in said tank between scifi overiow pipe and seid inlet pipe.

in witness whereof I have signed.y my name to this specification.
